We’re no strangers to learning about the existence of upcoming Windows Phone hardware when in-testing devices occasionally pop-up on apps like WP Bench. Most recently, a whole bunch of phones self-identifying as Nokia models have started appearing in its database, but there’s a good deal of controversy over which, if any, might be real hardware, and which could be the work of hoaxers.

According to WP Bench, the Nokia Phi, Nokia Pure Phi, Nokia Alpha, and Nokia PureLamda have run the app. Those names are very interesting, especially as we’ve been wondering just when and how Nokia’s PureView imaging technology would arrive on a Windows Phone handset.

The concern, though, is that everything but the Phi up there might be the work of copycats, as the Phi reportedly appeared first in the WP Bench listings, followed shortly thereafter by all the rest. Following a similar naming pattern following Greek letters, it wouldn’t take much work to come up with a whole bunch of phone names that looked like contemporaries of the Phi. All the “pure” stuff then, might be just an effort to get even more attention; the PureLamda looks especially tantalizing, claiming to be running Windows Phone 8.

Of course, there’s no way to know if the Phi itself is legit or not, either, so we find ourselves at a bit of an impasse when it comes to all of these names. Like so many other times before, we’ll keep these names in mind in case they show up again elsewhere, but until we get some more confirmation, don’t get too invested in seeing any of these models arrive.
